Technical Abstract

An example electronic device includes: a housing: a display including a plurality of signal lines; an optical sensor module including first and second light emitting elements respectively overlapping first and second signal lines, and a light receiving element configured to collect light from the first and/or second light emitting elements that is reflected and received from an external object; and a processor. The processor is configured to control the first light emitting element based on an off-time point of time of the first signal line corresponding to brightness of the display such that the first light emitting element emits light at a first light-emitting point of time, and to control the second light emitting element based on a time difference between off-time points of time of the first and second signal lines such that the second light emitting element emits light at a second light-emitting point of time.

Patent Claims
11 claims

Legal claims defining the scope of protection, as filed with the USPTO.

2

2. The electronic device of claim 1, wherein the optical sensor module further comprises a third light emitting element overlapping the first signal line of the display, and a fourth light emitting element overlapping the second signal line of the display.

4

4. The electronic device of claim 3, wherein the processor is configured to check the time difference between the off-time points of time of the first signal line and the second signal line based on the second reference distance.

6

6. The electronic device of claim 1, wherein the processor is configured to check the time difference between the off-time points of time of the first signal line and the second signal line based on a number of third signal lines disposed between the first signal line and the second signal line.

7

7. The electronic device of claim 1, wherein the processor is configured to set the first light-emitting point of time at which the first light emitting element emits light based on the off-time point of time of the first signal line corresponding to the brightness of the display and at least some colors of the display in which the first signal line is included.

8

8. The electronic device of claim 1, wherein the optical sensor module includes at least one of a camera, an ultraviolet (UV) sensor, an iris sensor, a spectral sensor, an infrared sensor, an RGB sensor, or a time-of-flight (TOF) sensor.

10

10. The electronic device of claim 9, wherein the optical sensor module is configured to check the first light-emitting point of time of the first light emitting element based on information related to the off-time point of time corresponding to brightness of the display provided from the display.

15

15. The method of claim 13, wherein the time difference between the off-time points of time of the first signal line and the second signal line are checked based on a number of third signal lines disposed between the first signal line and the second signal line.

16

16. The method of claim 13, wherein the first light-emitting point of time is set based on the off-time point of time of the first signal line corresponding to the brightness of the display and at least some colors of the display in which the first signal line is included.

17

17. The method of claim 13, wherein the optical sensor module includes at least one of a camera, an ultraviolet (UV) sensor, an iris sensor, a spectral sensor, an infrared sensor, an RGB sensor, or a time-of-flight (TOF) sensor.

19

19. The electronic device of claim 18, wherein the processor is configured to control the light emitting elements of the optical sensor module based on a duty cycle of the display within one frame based on the brightness of the display satisfying a designated condition such that the light emitting elements repetitively emit light the pre-defined number of times.

20

20. The electronic device of claim 18, wherein the processor is configured to set the light-emitting points of time of the light emitting elements based on off-time points of time of the display corresponding to the brightness of the display and at least some colors of the display.
